Description and Introduction

Fast / Super-Fast / Ultra-Fast Recovery Rectifiers # Introduction to the MURS140 Diode  

The MURS140 is a high-efficiency, ultra-fast rectifier diode designed for applications requiring fast switching and low forward voltage drop. As part of the MURS series, it is optimized for use in power supplies, inverters, and freewheeling circuits where rapid recovery and minimal energy loss are critical.  

Constructed with a planar epitaxial structure, the MURS140 offers superior performance in high-frequency operations. Its ultra-fast reverse recovery time ensures reduced switching losses, making it ideal for high-efficiency power conversion systems. The diode features a low forward voltage, enhancing thermal management and overall system reliability.  

With a maximum repetitive reverse voltage of 40V and a forward current rating of 1A, the MURS140 is well-suited for automotive, industrial, and consumer electronics applications. Its robust design provides excellent surge current capability, ensuring durability in demanding environments.  

Packaged in industry-standard SOD-123 or DO-214AA (SMB) form factors, the MURS140 is compatible with automated assembly processes, facilitating easy integration into modern circuit designs. Whether used in DC-DC converters or protection circuits, this diode delivers consistent performance and efficiency.  

Engineers and designers often select the MURS140 for its balance of speed, efficiency, and reliability in high-performance electronic systems.

Application Scenarios & Design Considerations

Fast / Super-Fast / Ultra-Fast Recovery Rectifiers

Alternative Part Number

  • ES1D --: 1A 200V ultrafast recovery rectifier in SMA package, directly interchangeable with MURS140 for most rectification and freewheeling applications.
  • US1D --: 1A 200V ultrafast rectifier in SMA from the same manufacturer, matching voltage and current ratings with similar recovery time.
  • RS1D --: 1A 200V fast recovery rectifier in SMA package, suitable drop-in replacement with comparable forward voltage and switching characteristics.
